Abstract: The present disclosure relates to a method for treating a solvent in wastewater generated in a polycarbonate production process. More specifically, the present disclosure relates to a method for treating a solvent in wastewater generated in a polycarbonate production process, which can easily recover a high purity solvent regardless of the concentration of the solvent by using a membrane distillation method to reuse it, and contribute to energy savings.

Abstract: Disclosed are an adsorptive permeation hollow fiber membrane formed by uniformly dispersing an adsorbent capable of selectively adsorbing only a specific gas in mixed gas components inside a porous hollow fiber membrane having a sponge structure capable of non-selectively permeating a mixed gas in a powder or crystalline powder form, a method of manufacturing the same, and a gas adsorptive/desorptive separation system utilizing the same.
